Difference between Conductive Carbon Black and Acetylene Carbon Black

The main differences between conductive carbon black and acetylene carbon black lie in their conductive properties and production methods.

Conductive Carbon Black:

Conductive carbon black is a generic term referring to a special type of carbon black with higher conductivity than regular carbon black or pigment carbon black. Based on their conductivity levels, they can be classified as CF Conductive Carbon Black, SCF Super Conductive Carbon Black, XCF Extra Conductive Carbon Black, and Acetylene Carbon Black. In terms of production methods, they can be categorized as acetylene carbon black, furnace black, and by-product carbon black.

Acetylene Carbon Black:

Acetylene carbon black is a type of conductive carbon black. It is typically produced by converting acetylene, obtained from carbide, into high-performance carbon black. The process involves purifying acetylene gas and subjecting it to high-temperature thermal cracking in the absence of air, followed by cooling and collecting the resulting high-performance carbon black, commonly known as acetylene black.

- Chemical Formula: C

- Atomic Weight:12.0107

- Appearance:Pure black powder and granules

- Quality Standard: GB/T3782-2006

- Particle Size:35-45nm

- Oil Absorption Value:220-330ml/100g

Compared to other carbon blacks, acetylene carbon black has the following characteristics:

- Light weight with small specific gravity

- Large surface area and strong adsorption capacity

- Stable chemical properties

- High surface activity and conductivity

- High purity with low ash and volatile content

In contrast to powdered acetylene black, granular carbon black has advantages such as small volume for easy transportation, low dust pollution for improved working environments, good flowability, and dispersibility. Acetylene black is mainly used for functions such as conductivity, thermal conductivity, antistatic properties, coloring, and reinforcement.
